Logger

Playwright 生成大量日志，并且可以通过插件化日志器接收器访问它们。

¥Playwright generates a lot of logs and they are accessible via the pluggable logger sink.

const { chromium } = require('playwright');  // Or 'firefox' or 'webkit'.

(async () => {
  const browser = await chromium.launch({
    logger: {
      isEnabled: (name, severity) => name === 'api',
      log: (name, severity, message, args) => console.log(`${name} ${message}`)
    }
  });
  // ...
})();
